Why are men so angry?

I have been reading a lot about the incel sub. I have read a few threads. I have also seen the comments. I understand why men would be angry. I really do. I have been watching a show called, "The Killing of Two Lovers". The story is about a young man who attempts to murder his wife and son to start a new life. He is unhappy about being in a marriage. He feels trapped and doesn't know what to do. I think he is mentally ill. I am not sure. But what I do know is that men have it really tough out there. They have to work and struggle to find money and food. They are lonely, they have difficulty making friends. They have a very hard time finding a sexual partner. They are also lonely. It seems like these young men are really struggling. I know that not all of them are this way, but I believe that a lot of them are. I also think that we should be kind to these young men. I am not saying that it's okay to be angry and violent. But I do think that we should be kind to these men.
